        {

            int number, sum = 0, n;

            Console.Write("enter the Number");

            number = int.Parse(Console.ReadLine());

            n = number;

            for (int i = 1; i < number; i++)

            {

                if (number % i == 0)

                {

                    sum = sum + i;

                }

            }

            if (sum == n)

            {

                Console.WriteLine("\n Entered number is a perfect number"); //6

                Console.ReadLine();

            }

            else

            {

                Console.WriteLine("\n Entered number is not a perfect number");

                Console.ReadLine();

            }

        }
